Description

A 4 sq mm solar cable is a specially designed electrical cable used in solar power systems to connect photovoltaic (PV) panels to inverters or charge controllers. With a cross-sectional area of 4 square millimeters, it offers low resistance and efficient current flow, making it suitable for medium-capacity solar setups. The cable is typically UV-resistant, weatherproof, flame-retardant, and double insulated, ensuring safety and durability even in harsh outdoor environments. It is rated for high DC voltages (up to 1.8 kV) and temperature variations, and complies with international standards such as TÜV and IEC for solar installations.
